 Question 337161: I am trying to figure finding slopes, if it exists, of the line containing the pair of points. However I do not know what the and in the equation means? for example (8,4)and(9,-9) trying to find slope m= Can you help explain what this is please? Thanks MaryFound 2 solutions by jim_thompson5910, stanbon:Answer by jim_thompson5910(28696)   (Show Source): You can put this solution on YOUR website! Start with the slope formula. Plug in , , , and Subtract from to get Subtract from to get Reduce So the slope of the line that goes through the points and is If you need more help, email me at jim_thompson5910@hotmail.com Also, feel free to check out my website. Jim Answer by stanbon(57940)   (Show Source): You can put this solution on YOUR website!(8,4)and(9,-9) trying to find slope m= ============== slope = (change in y)/(corresponding change in x) ---------------- m = (-9-4)/? Notice the order in which the y-values were selected. You MUST use the same order in selecting the x-values m = (-9-4)/(9-8) m = -13/1 m = -13 ============== Cheers, Stan H.
